- shoes, of which the following is a specification.

This invention relates to an improvement in horse shoes;

The primary object of the invention is to provide a horse shoe with aremovable calk, in which the calk is supported on the shoe andeffectually held against displacement without the use of bolts or otherremovable securing devices which have a tendency to work loose and whichrequire considerable time in placing the call: on the shoe.

Another object of the invention is to so construct the securing meansthat the constant pounding of the calk will tend to tighten the securingmeans.

In the drawings: Figure 1 is a plan view of a horse shoe with the calksarranged thereon. Fig. 2 a side elevation. Fig. 3 a section on the line33 of Fig. 1. Fig. 4. a detail view of the calk. Fig. 5 is a perspectiveview of a modified form of calk.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

In the drawings, 10 designates the shoe which at its toe portion isprovided with spaced ribs 11 and 12. Formed in the shoe at the sides ofeach rib and adjacent the base thereof are pairs of parallel extendinggrooves 11 and 12', each pair opening upon opposite sides of the shoeand each of said grooves having its wall adjacent the rib, undercut, asclearly shown in Fig. 2 of the drawings. The shoe is also provided atits heel portion with ribs 13 and 14, adjacent the base of each of whichat the sides thereof are provided pairs of parallel extending grooves 18and 14, each pair of which extends throughout the width of the shoe. Theribs are formed integral with the shoe, although the same could besecured to the shoe in any suitable manner. However, in practice, theconstruction illustrated has been found more effectual from thestandpoint of manufacture as well as from the standpoint of efiiciencyin operation. These ribs are substantially round in cross section,

the ribs 13 and 14 extendingentirely across the sides of the shoe.Disposed adjacent each rib and intermediate the ends of the ribs is adepression 15', the function of which will be hereinafter described.

The calks consist of'substantially rectangular blocks 16 which are eachprovided throughout their length with a longitudinally extending groove17, the grooves being substantially circular in cross section andopening through the upper face of the block, whereby the blocks may beplaced on the ribs carried by the shoe and defining on each side ofthe'block a longitudinally extending tongue, the inner wall of each ofwhich is undercut as shown. In securing the blocks which constitute thecalks to the shoe, they are first placed upon the ribs with their upperextremities engaging within the grooves formed in the shoe at the baseof each rib, the grooves in the blocks being of substantially the samecross sectional design as the ribs. After the blocks have been assembledon the ribs with their end portions alining with the ends of the ribs, aportion of the block is forced into the depression 15 formed in theshoe. This is accomplished by means of a punch or any suitable tool, aportion of the metal of each of the blocks being securely lodged in thedepression 15 as well as forced into binding contact with the rib, thepunch directing the metal not only toward the shoe but toward the rib.It will be obvious that this arrangement effectually prevents the calkfrom spreading.

In order to facilitate the operation. of engaging a portion of the metalof each of the blocks within the adjacent depression 15, each of saidblocks has formed in one side face thereof an inwardly extending slotarranged to come into alinement with the adjacent depression 15 when theblock is positioned upon one of the ribs 11. As is best shown in Fig. 3of the drawings, each of said slots terminates at its inner extremity ina shoulder which may be readily engaged by a punch or other tool toforce the metal of the calk into locking engagement within the adjacentdepression.

Particular attention is called to the fact that in use the constantpounding will tend to more securely force the projecting portion 18 ofthe call: in contactwith the shoe and bring the grooved portion of theshoe into binding engagement with the ribs. This binding action may beincreased by forming the block which constitutes the calk, slightlywider adjacent its face which contacts with the ground, as illustratedin Fig. 5 of the drawings. In this figure, I have illustrated a modifiedform of my invention as showing a tapered block 19, this blockconstituting the calk. The block' is slotted at 20 in the same manner asdescribed with reference to the preferred form of the invention, and inthus forming it wider at its outer face, an increased tread surface isprovided.

The many advantages of a construction of this character will be clearlyapparent as it will be noted that it provides an effectual calkattaching means which may be economically constructed and in which thecalks may be quickly and securely attached to the shoe. lhe ribs 11 and12 at the toe of the shoe are spaced, whereby the shoe may be sizedwithout distorting the calks.

Having thus described the invention what is claimed as new is:

l. A horse shoe having a rib formed thereon and being provided with adepression adjacent said rib, and a calk mounted on the rib, said call:having an inwardly directed slot formed in one side face thereof inalinement with said depression and providing a horizontally arrangedshoulder at the inner extremity of the slot whereby a tool may be iengaged with said shoulder to force the metal of the call: adjacent saiddepression into locking engagement within the depres sion.

2. A horse shoe including a body portion of substantially uniformthickness throughout its entire area, the said body portion at the toehaving an upstanding rib formed thereon and having a slot formed in theadjacent face thereof upon each side of said rib, the said slots openingthrough the outer edge of the shoe and said shoe having a recess formedtherein medially of said rib, and a calk arranged upon said rib andengaging within said slots, the said call: being disposed entirelywithin the lines of the body portion of the shoe and having a verticallydisposed slot formed in one side face thereof terminating at its innerextremity in a horizontally arranged shoulder whereby a punch or othertool may be readily engaged with said shoulder to force the metal of thecalk into locking engagement within the re cess formed in the shoe.

In testimony whereof I affix my signature in presence of two witnesses.
